HTTP compression is a capability that can be built into web servers and web clients to make better use of available bandwidth, and provide faster transmission speeds between both. HTTP data is compressed before it is sent from the server: compliant browsers will announce what methods are supported to the server before downloading the correct format; browsers that do not support compliant compression method will download uncompressed data. The most common compression schemas include gzip and deflate, however a full list of available schemas is maintained by IANA
